This study was carried out to find out changes in regional cerebral blood flow(r-CBF) in relation to(i) clinical status of patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms ; (ii) the degree of subarachnoid hemorrhage as indicated by brain CT scanning ; (iii) the severity of angiographic vasospasm, and (iv) other neuropathological condition. Measurement of r-CBF were performed, using 133Xe inhalation method, on 50 patients with ruptured intracranial aneurysms. Some of the major findings were as follows : 1) The degree of abnormalities of blood flow correlated well with the clinical severity of neurological deficits. 2) A marked reduction in r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF decreases below 30ml/100gm/min in almost all of the patients, and severity of vasospasm correlated with the decrease of CBF. 4) The measurement of CBF on patients with subarachnoid hemorrhage was thought to the useful for foreseeing the clinical outcome of the patients.

Recent technological advances in ultrasound instrumentation have resulted in equipment that will image in "real-time" slices of the human brain similar in quality to computerized tomography(CT). Multiple authors have attested to its usefulness in locatin, characterizing, and facilitating in the biopsy or removal, or both, of intracerebral masses. In this study, the author has examined the efficacy of intraoperative neurosurgical ultrasound in 18 patients who were admitted to the Department of Neurosurgery, Kyung Hee University Hospital. The results were as follows : 1) It can provide critical assistance in precise localization of subcortical masses, since in many instances the overlying surface of brain provides no clue for localization. 2) This technique is very useful for the identificantion of deep lesions, provding infromation about their solid and cystic components and about the shortest route of access to tumor. 3) It provides precise information to help guide biopsy needles into deep lesions, and to confirm their presence within the lesion itself. 4) The system is highly accurate in visualizing ventricular catheters during and after their placement. 5) The system is inherently safe for the patient and the operating room personnel since there is no radiation exposure.

The presnt study was carried out to find out any difference in terms of the rate of rebleeding, mortality and of the occurrence of vasopasm and hydrocephalus between the two groups of patients with subarachnoid hemorrhage : a group of 225 cases which were administered with epsilon aminocaproic acid(EACA) (antifibrinolytic agent) and the other a group of 221 cases without EACA treatment. Both groups were chosen from 476 patients admitted to the Department of Neurosurgery, Kyung-Hee University Medical Center within 7 days after the onset of subarachnoid hemorrhage during a period from January 1982 to December 1987. The clinical observation was done during acute period following subarachnoid hemorrhage. The major findings obtained were as follows : 1) The occurrence of rebleeding was higher within 3 days after the onset of subarachnoid hemorrhage. The rate of rebleeding was 8.4% in treated group whereas the rate was 13.1% in control group. This may suggest that administration of EACA is effective to prevent rebleeding. 2) the occurrence of vasopasm was higher within on the 7th and 8th day after the onset of subarachnoid hemorrhage. The rate of vasospasm was 28.9% in treated group whereas the rate was 12.4% in control group. This means that the rate of occurrence of vasospasm was two times higer in EACA treated group. 3) the rate of occurrence of hydrocephalus was 18.3% in treated group whereas the rate lower in control group(11.6%). 4) Within-two-weeks mortality and within-one-month mortality were 14.7% and 22.2% respectively in treated group whereas the two rates in control group were 15.1% and 24.1% respectively. No significant difference between the two groups was observed. 5) The causes of death in treated group were found to be vasospasm(55.5%) and rebleeding(28.0%) in order, whereas in control group the causes of deaths were rebleeding(40.2%) and vasospasm(21.3%). In other words, the main cause of death was vasospasm in treated and that in control group was rebleeding.

The authors analyzed 60 cases of ruptured internal carotid artery(ICA) aneurysms admitted and operated at Department of Neurosurgery in Kyung Hee University Hospital during the period from July 1983 to June 1988. The results of analysis were summarized as follows; 1) Mean age of patients was 51 years. ICA aneurysms occurred more frequently in female(47) than male(13). 2) Distribution of ICA aneurysms were ophthalmic aneurysm 8 cases(13.3%), posterior communicating aneurysm 40 cases(66.6%), anterior choroidal aneurysm 7 cases(11.6%), bifurcation aneurysm 5 cases(8.3%). 3) Most common direction of aneurysmal dome in ophthalmic, anterior choroidal and posterior communicating aneurysm was posterior-inferior-lateral and in bifurcation aneurysm was posterior-superior. 4) Multiple aneurysm was 23 cases(38%). 5) Incidence of clinical vasospasm was 48.3% and that of rebleeding was 20%. 6) Clipping was done in all cases, 2 cases combined with wrapping and 2 cases with trapping. 7) Mortality rate was 21.6%.

42 knees with degenerative arthritis underwent arthroscopic lavage and 7 knees underwent arthroscopic lavage combined with multiple bone drilling in between 1994 and 1995 and followed average 12 months. Clinical evaluation using the hospita1 for specia] surgery knee scores (HSS scores) was done at last follow up and classified into 4 groups: excellent (90-99), good (80-89), fair (70-79) and poor (less than 70). The results were as follows: l. Of the 42 knees of the lavage group, 6 knees (16%) was excellent, 14 knees (33%) good, ]7 knees (40%) fair and 5 (11%) knees poor. Success group (Excellent & Good) were achived in 20 knees (49%). 2. Of 17 knees treated with arthroscopic lavage comhined with multiple bone drillig resulted in excellent in 9 knees (53%), good in 4 knees (23%), fair in 2 knees (12%) and poor in 2 knees (12%). Success group were achived in 13 knees (76%). 1n conclusion, we helieve that multiple bone drilling in conjunction with arthroscopic lavage has more favorable effect on the pain relief for degenerative osteoarthritis of the knee than arthroscopic lavage only.
